Title: Recycling polyethylene@ polypropylene@ or polystyrene adhesive label scrap - by mixing with adhesive-free polymer and communicating to give prod. for packaging, agricultural film etc. mfr.
Inventor: MUELLER-STRAUB JOACHIM DIPL IN
IPC: B29B17/00
Filed: 1992-07-02
Abstract: Recycling of adhesive-contg. ethylene, propylene or styrene polymer waste material is by comminution together with adhesive-free scrap of the same or similar polymer material so that the 2 types of material are mixed together. In particular, the materials to be comminuted are in the form of a roll of adhesive-contg. material on a core of adhesive-free material, such rolls being claimed per se, esp. where the core is of material already recovered in the claimed recycling process. Pref. the materials to be recovered are polyethylene and polypropylene and can be LDPE opt. contg. 0.5-10 (pref. 1-5) wt.% HDPE, polypropylene and/or EVA copolymer. At least 1, esp. 3-10, pts. wt. adhesive-free material is used per pt. wt. adhesive-contg. material, the amt. of adhesive in the recycling material being 0.5-5 (esp. 1-3) wt.%. USE/ADVANTAGE - The amt. of adhesive-free material is such as to prevent stoppage of the comminution appts. and such as to remove any adhesive deposited on the appts. The comminuted material (esp. granulate) can be extruded or injection moulded to give films (e.g. for agricultural use), pipes, bags, mouldings or cable-coverings, such articles being wholly of the recycled material or being composites with virgin polymer, such virgin polymer opt. being present as surface material on a core of recycled material. The recovered adhesive is used as a plasticiser for thermoplastics, esp. for polyolefins contg. at least same HDPE (claimed).

Title: Washing machine inlet valve calibration - using separate measurement for the flow vol. and trickle flow vol.
Inventor: STILLER THOMAS DR ING
IPC: D06F39/08
Filed: 1992-07-07
Abstract: To calibrate the electro-mechanically operated inlet valve for a domestic appliance using water, such as a clothes or dishes washing machine, the flow vol. and a trickle flow vol. at the inlet valve (2) are determined by two separate and successive measurements. During the first measurement, the flow vol. is established as a given filling time for a set measured vol. During the second measurement, the inlet valve (2) is controlled at a given and constant valve operation cycle time to measure the trickle flow vol.. Pref. the cycled control of the inlet valve (2) is continued until the filled vol. has been achieved. The number of operating cycles gives the trickle flow vol.. The valve cycle time is greatly less than the filling time. USE/ADVANTAGE - The system establishes precisely the vol. to fill the machine, and the trickle flow vol. from the time the closing valve is operated until the flow is blocked, eliminating faults.

Patent DE-4228391-A1 (DE)
Inventor: BORGARDT GEB HAZAY
IPC: B32B7/06
Filed: 1992-08-26
Abstract: A container made of recyclable plastics is manufactured in a simple and economic manner by co-extrusion then by thermoforming. The container has a wall made of a support layer (11), an inner layer (12) and if required at least one additional layer (13-18), which adhere to each other. Certain layers may be separated by applying a predetermined force. The inner layer (12) and if required an additional layer (13) or layers (13-18) protect the support layer (11), which constitutes the major part of the container material, from contamination with the filling material. The support layer (11) may thus be preserved in its pure form and can be recycled in the manufacture of new, high-quality products, once the filling material has been emptied and the inner layer (12), as well as any additional layers (13-18), have been removed. A collecting and transporting container for said containers allows them to be effectively collected, transported and recycled. A process for manufacturing said container in a simple and economic manner is also disclosed.
